January 24-26 Potential Winter Storm

I am monitoring the threat for accumulating snow from January 24th to January 26th.

The GFS and ECMWF models are now hinting at a strong storm system crossing from the Central Plains east into the Midwest or Great Lakes. At the moment, there is a difference between the two, with the American GFS model taking the system into Chicago and the European ECMWF model taking the system into the US/Canada border in the Western Great Lakes. The map I drew above went by the GFS model for the sole purpose of covering all possibilities as far as who has at least a chance of getting snow at the moment. If this storm does happen and the models are correct, I would expect a good accumulation event occurring in the North Plains and Upper Midwest, possibly in the Great Lakes. The GFS model shows a fair accumulation event above 4 inches for some people in the Northeast, so that threat will need to be monitored.

This is as good as it gets- confidence is too low to outline anything else otherwise you would have seen it.

The dates make me cringe. Happy 35th anniversary, Blizzard of '78.
